What is Tourette Syndrome?
Tourette Syndrome (TS) is an inherited neurological disorder characterized by repeated involuntary movements and uncontrollable vocal sounds called tics. In a few cases, such tics can include inappropriate words and phrases. The symptoms of TS usually appear before the individual is 18 years old. Although TS symptoms range from very mild to quite severe, the majority of cases fall into the mild category. The first symptoms of TS are usually facial tics - commonly eye blinking. With time, other motor tics may appear, such as head jerking, neck stretching, foot stamping, or body twisting and bending. It is not uncommon for a person with TS to continuously clear his or her throat, cough, sniff, grunt, yelp, bark, or shout. A person with TS may touch other people excessively or repeat actions obsessively and unnecessarily. A few patients with TS demonstrate self-harming behaviors such as lip and cheek biting and head banging. persons with TS can sometimes suppress their tics for a short time, but eventually tension mounts to the point where the tic escapes. Tics worsen in stressful situations and improve when the person relaxes or is absorbed in an activity. TS is diagnosed by observing the symptoms and evaluating family history. Tics must be present for at least one year. TS is a clinical diagnosis.
Is there any treatment?
The majority of persons with TS require no medication, but medication is available to help when symptoms interfere with functioning. TS medications are only able to help reduce specific symptoms. Neuroleptic and antihypertensive drugs can have long- and short-term side effects, and use of stimulants is controversial. Relaxation techniques and biofeedback may be useful in alleviating stress.
What is the prognosis?
There is no cure for TS; however, the condition in A lot of individuals improves as they mature. Individuals with TS can expect to live a normal life span. Although TS is usually lifelong and chronic, it is not degenerative. In a few cases, complete remission occurs after adolescence.
Is there Research Being Done?
Investigators are conducting genetic linkage studies in large multigenerational families affected with TS in an effort to find the chromosomal location of the TS gene(s). Understanding the genetics of TS will directly benefit patients who are concerned about recurrence in their families and will ultimately help to clarify the development of the disorder. Investigators also are studying certain neurotransmitters to explore the role they play in the disease process and develop more effective therapies. Others are researching how environmental factors may influence the expression of the disease.
